Regardless of the language, you can always resort to the JSONRPC to interact with the network.

Oh ok. Thanks. I tought that there are naybe some dedicated libraries for it, as they are for js. – NewTwoEth Apr 06 '17 at 05:34

Yep, I tried to find the library too, but sadly there isn't a popular one for cpp. – Yuanfei Zhu Apr 06 '17 at 06:26

3The library could be just based on libjson-rpc-cpp, as this is what cpp-ethereum is using. – NewTwoEth Jun 26 '17 at 23:43

@NewTwoEth does not support ipc connection unlike full fledged web3. This expose to the problem of not knowing to which pubsub subscription the response you re receiving corresponds to (when you have several differrent ones). – user2284570 Dec 08 '20 at 12:21
